Analysis of Existing Scenario of Sewerage Management in Gurugram and Forecasting its Future Demand
Abstract: AbstractWater, food and shelter are the basic needs of human beings but now become inaccessible resources. Due to the increasing demand for these resources, it cannot be met successfully by the conventional sources of energy. Indiscriminate rises in population imply industrialization, migration and the need for energy which leads to the environment degraded. In India, there are 113 river and vast alluvial basins to hold the groundwater. But due to …
